Сложные преобразования JSON в объект DataTable в C#

---

Привет,
PFA ниже json преобразуется в datatable в c#.

Пожалуйста, помогите мне срочно.

{"TotalPurchaseOrders":1,"PurchaseOrders":[{"RN":"16872","OD":"2017-12-25T13:41:51.637","RD":"2017-12-25T13:41:53.693","Status":"UPDATED","CD":null,"VC":"BIWL","VN":"LLPL Bhiwandi Depot","CST#":"","TIN#":"","InvNum":"","Partials":[{"DD":null,"DV":0.0,"SAH":0.0,"Other":0.0,"InvNum":"","Notes":"","Items":[{"PC":"TGFB100","HSN":"3305.10.90","PN":"TIGI SF SERIOUS COND 750ML","MRP":3000.0,"RQO":0,"CQO":1,"UPO":1992.14,"OTB":[{"TC":"SGST/UTGST 14%","TA":278.9000},{"TC":"CGST 14%","TA":278.9000}],"OTN":"SGST 28%","OT":557.8,"RQD":0,"CQD":1,"UPD":1992.14,"DTD":0,"DVD":0.0,"DT":557.8,"DTB":[{"TC":"SGST/UTGST 14%","TA":278.9000},{"TC":"CGST 14%","TA":278.9000}],"DTN":"SGST 28%","Notes":""}]}]}],
"Ошибка":null}

Что я уже пробовал:
